Answer:
8 bulbs
Step-by-step explanation:
Step one:
Given data
Shelia buys flower bulbs from a catalog for $2 each and $4 shipping charge for the whole order
we are told that the total money spent is $20
let the number of bulbs ordered be x, and the total money spent be y
the equation for the situation is
y=2x+4
for a total amount of $20, we want to find x
20=2x+4
20-4=2x
16=2x
divide both sides by 2
x= 16/2
x= 8 bulbs

4. Christina made a graph to describe the distance she walked on her back packing trip. She plotted miles on the y-axis and the number of days on the x-axis. She graphed a point at (0,0) and another point to show she walked 14 miles in 8 days and drew a line that passes through the points. What is the slope of the line?
Step-by-step explanation:
We have the points (0, 0) and (8, 14).
Rise between the points = 14 - 0 = 14.
Run between the points = 8 - 0 = 8.
Slope of Line
= Rise/Run = 14/8 = 1.75.

When we talk of the slope in this case, we are simply talking of the amount he needs to save for each of the months
As we can see, for the initially, he had 900 to save, so what this mean is that at the very beginning, the amount of money he had to save is 900
Hence, the total money he had to save is $900 and this makes the second option correct

The corners of a triangle garden are marked with trees at coordinates (0,3),(3,0), and (4,3). Let a denote the area of the garden, in square units. Which of the following is true?
Given:
Three corner points of a triangular garden are (0,3),(3,0), and (4,3).
To find:
The area of the garden.
Solution:
We know that, area of a triangle is
[tex]A=\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]
Let a denote the area of the garden, in square units.
Three vertices of the triangular garden are (0,3),(3,0), and (4,3). So, area of the triangular garden is
[tex]a=\dfrac{1}{2}|0(0-3)+3(3-3)+4(3-0)|[/tex]
[tex]a=\dfrac{1}{2}|0(-3)+3(0)+4(3)|[/tex]
[tex]a=\dfrac{1}{2}|0+0+12|[/tex]
[tex]a=\dfrac{1}{2}\times 12[/tex]
[tex]a=6[/tex]
Therefore, the area of the garden is a=6 square units.

d. Determine the cost of tarpaulin, if it measuring 1 m2 costs Rs. 5 .
What is the distance, rounded to the nearest tenth, between the points (-2.4) and (6,-4)?
Answer:
[tex]distance = \sqrt{(x _{1} - x _{2})^{2} + {(y _{1} - y _{2})}^{2} } \\ = \sqrt{ {( - 2 - 6)}^{2} + {(4 - ( - 4))}^{2} } \\ = \sqrt{64 + 64} \\ = \sqrt{128} \: units[/tex]
A company has two factories, factory A and factory B. The cost per item to produce q items in factory A is
200 + 3/q
q
. The cost per item to produce q items in factory B is
300 + q/
3q
. Find an expression for the sum of these costs per item. Then divide this expression by 2 to find an expression for the average cost per item to produce q items in each factory.
The average cost per item to produce q items in each factory is
Answer:
(700 + 51q)/4qStep-by-step explanation:
Given costs:
(200 + 13q)/q and (300 + 25q)/2qSum of the costs:
(200 + 13q)/q + (300 + 25q/2q) =(400 + 26q)/2q + (300 + 25q)/2q =(700 + 51q)/2qAverage cost is sum divided by number:
(700 + 51q)/2q ÷ 2 = (700 + 51q)/4qsomeone HELP

Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments. How can she sort the beads so the compartments in each case hold the same number of beads and none are left over?
Answer:
5.7 beads
Step-by-step explanation:
Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments.
We are told in the Question that:
the compartments in each case hold the same number of beads and none are left over
Hence, let the number of beads in each compartments = x
Therefore:
8x + 6x = 80 beads
14x= 80 beads
x = 80 beads/14
x = 5.7142857143 beads
x ≈ 5.7 beads
Hence, she can sort the beads into 5.7 beads per compartments

Estimate the sum of 945 + 573 + 617 by rounding each number to the nearest hundred.
The estimated sum of 945 + 573 + 617 by rounding each number to the nearest hundred is 2100.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Are the sum of three integers 945, 573, and 617.
Now, 945 rounded to the nearest hundred is 900, 573 rounded to the nearest hundred is 600 and 617 rounded to the nearest hundred is 600.
Therefore, the sum of 945 + 573 + 617 by rounding each number to the nearest hundred is 900 + 600 + 600.
= 2100.

On a highway, you take 3 seconds to increase your speed from 32 to 35 miles per hour. Your speed increases the same amount each second. The speed limit is 65 miles per hour. What is the domain of the function?
Answer:
1 to 30 seconds
Step-by-step explanation:
3 seconds increases your speed from 32 to 35 miles per hour
Hence 3 seconds = 3 miles per hour(35-32 miles)
1 second = 1 mile
The function for the increase per mile is therefore:
f(x)= 1x
Where x is number of seconds travelled on the highway
The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)
If J M = 9 and K M = 4 , what is the approximate perimeter of Δ J K L ? 26.2 26.2 29.8 29.8 31.0 31.0 31.7
Answer:
Correct option is (a)
Step-by-step explanation:
According to question in the triangle ΔJKL
JK = 9 and KL =4
according to the condition of triangle sum of two sides must be greater than the third side
Here sum of its two sides is 9 + 4 = 13
⇒ third side must be greater than 13 say 13.2 = JL
therefore, perimeter of triangle ΔJKL is
JK + KL + JL = 9 + 4 + 13.2 = 26.2
Therefore correct option is (a)

Find the value of x in each diagram
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.

85 points! Sketch the following image on a blank piece of paper and rotate triangle ABC 80 degrees. 1st pic attached: is the triangle and 2nd pic attached is what I drew.... did i do it right?
Answer:
Step-by-step explanation:
It can never be perfect, but what I see, I think yes, because u didn't rotate it 90 degrees since it's not a right triangle, but u did rotate it where it looks close to 90 degrees, so it does look like its 80 degrees as a rotation. Question, does it not say how to rotate it? Like 80 degrees clockwise, or 80 degrees counterclockwise?
Hope this helped!
